Got a new laptop, dont know how good it really is.

Hello, I just got a new laptop, a Medion Akoya p7631 with i5-4210m,
8GB of Ram and a dedicated GT 825m. And kind of got out of the loop, with specs and stuff since I had last upgraded like 3 years ago. So Ive been playing a couple of games, and I thought I could push the graphics a bit higher, but it doesn't seem to be playing that smoothly. So just asking If maybe the quality isn't that good or I don't know. Would Like to maybe know if its the settings or whatnot.
